CORPORATION OF OHIO IPII .AND CHIMNEY CONNECTION .Application led March 25, 19.30. Serial No. 438,817.

This invention relates to pipe andl chimney connection and has special reference to a pipe and chimney connection forming the intake for a chimney, stack or the like of the type the Serial Number 438,087.

. One important object of the invention isto provide an improved pipe and chimney'connection arranged for the connection of one l0 or more smoke pipes and'fadapted to be lo cated within a chimney. A second important object of the invention is to provide a device ofI this description arranged to receive the flowing gases from a smoke pipe and conduct them into chimney or the like without the production of eddy currents and in such manner that a smooth and uninterrupted flow of the gases will be obtained thereby promoting draft.

y A third important object of the invention is to provide a device of this character having a gcombustion chamber so as to ensure `practically completo combustion of all combustible matter in gaseous, vaporized or solid states before entering the' chimney proper.

A fourth important object of the invention .is to provide means in such a device to permit the removal of soot and the likefrorn the device.

A fifth important objectof the invention is to `provide'an improved combination of such a pipe and chimney connection with a soot receiving receptacle.

A sixth important object of-the invention is to provide a novel device of this character adapted not only for connection of one or more smoke pipes of ordinary size but also for connection of one or more smaller pipes such as are used in connection ywith gas stoves, gas heaters and the like.

With the above and other objects in view, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated. inthe accompanying drawings and specifically claimed.

In the accompanying drawings, like characters of referenceindicate like parts in the several views, and

Figure 3 is a perspective view of the pipe chimney; Y

Figure 4 is a reducedscale section similar to Figure 2 but showing a slight modification o of the invention;

Figure 5 is a detaillplan view illustrating the manner of connecting twosmoke pipes to the pipe and chimney connection.

The embodiments of the invention here shown are not to be understood as other than certain preferred-forms Vand thevinv'ention,

ture being substantially This curved portion merges at f its forward end into -a vertical front wall 12.` The casting also has ay vertical front wall 13 at its upper end and fromthe lower end of this wall extends (in the form shown in Figure 2) a forwardly i11- clined front wall 14, the lower edge of which also joins the front wall 12. In the form shown in Figure 4 the wall 14 is replaced by an arcuate wall 15. The walls just described are joined by side walls 16 'which' are perpendicular to the front and'back walls. VThe upper edges of the walls 10, 13 and 16 all lie in the same horizontal plane. Thus the upper part of the device forms a rectangular portion of proper size to fit within the flue F of a chimney C. A f

The front wall 12 is providedy centrally with an openingy around which is a forwardly v extending annular iiange 17 the forward edge the purpose specified.

of which forms a seat Jfor the flange 18 of a smoke pipe nipple 19,bolts 2O serving to hold the nipple in place. This nipple may either be straight as in Figure 2-for connection of connection is much greater than lthe pipe area Y so that, just back of the nipple the casting is both wider and higher than the diameterv of the pipe. Also, if a plane be passed Aat 45OA through the wall 11 and its center of curvatures it will be found that the distance be@ tween walls 11 fand 14 is greater than the distance between Walls 10 and `13. -V Thus gases 'entering through the nipple will flow smoothly up into the chimney and nochecking or back pressure will be produced thus promoting an efficient draft. AFurther the presence of the enlarged portion just behind the nipple permits the gases to move slowly at this point ,and promotes the completion of combustion in any unburnt gases. j Y A y j In the ,wall `11 is anlopening 2l which is closed by a door 22 hinged at 23 to the rear portion of'the Wall 1,1. A latch 24 is provided at the forward edge of the opening to hold the door closed and it is to be noted that the door is curved to conform to the curvature of the wall ll so as not to intertere with the smooth'flow of gases. i The Ainterior corner of all meeting walls are joined by curved surfaces 25 to eliminate all sharp Acorners and the interference caused thereby. Y

The curved portion of the pipe and chimney connection is seated in the open upper end ofa soot receptacle 26 which is held in `the lower part of the chimney, C, and is provided with a` suitable cleanout door 27 here shown as a iiat metal plate having lateral lugs 28 fitting L-shaped brackets 29 cast on the front of the receptacle 26. This door isv opened by simply lifting the same byV its ,handle 30' to free the lugs from the brackets whereupon it may be moved away bodily from the soot receptacle. j

In the front wall 13 there may be .provided a suitable opening to receive the inner end of a nipple3l provided with a iiange 32 wherethrough extend bolts 3.3 by means of which Ythe'nipple is secured in place. This nipple is of Vflaring form sov that it may'receive the delivery end .of a small pipe such` as vmay .lead from a gas heater or stove.`

f A modified :torin'of joint between the pipe and chimney connection and soot receptacle is shown* in Figure '6 in the form of the shoulder ll.

There has thus been provided a simple and eliicient device of the kind described and for It is bvioiis that changes may be made in joined by a cylindrical wall having its axis transverse the connection, said connection having parallel side walls and the internal cross sectional area of the portion between the intake and delivery ends being greater than the internal cross sectional area of the respective ends. y A, 2. ,A pipe and chimney connection having' one end adapted for connection to ya smoke pipe and the other 'end adapted toenter a chimney and extend upwardly therein, said rconnection being expanded between said ends to provide a combustion chamber and thereby promote complete combustion of partially consumed and unconsumed fuel owing .from the smoke pipe, the bottoni .and rear of the expanded portion being curved to` provide free and uninterrupted iow of gases through the connection whereby to promote draft. n
